CURTAIN-WINDOW.

Specification of Letters Patent. Patented Dec. 27, 1921.

A ppllcation filed December 11, 1917. Serial No. 208,628.

To all whom it may concern:

Be it known that I, Crnmnns F. Pansron, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new, and useful Improvements in Curtain-\Vindows, of which the following is a specification.

My invention is intended more particularly for use in the flexible curtains of auto mobiles although, as will appear from the following description, it is also useful in other relations where a window is to be videdin flexible material. The object of the invention is to provide a mounting for a glass window which will securely hold the same in position in the curtain without rattling, which will not tear or deface the curtain, which will present a neat and attractive appearance and be inexpensive to manufacture and readily applied.

Inthe accompanying drawing Figure 1 is an interior elevation of a section of a curtain showing my invention applied thereto; and Fig. 2 is a cross section on an enlarged scale through the glass window, the frame by which it is attached to the curtain and a portion of the curtain.

In Fig. 1 the window is shown as elliptical, though obviously it may be made of any other desired shape. The glass 3 may be plate or other glass suitable for forming a window, and is immediately surrounded by a frame 4 of substantially the same thickness as the glass, the material being wood, fiber or other material having the required rigidity, though preferably a fairly light material is employed. The interior opening of the frame is shaped to fit the glass quite closely, and the glass is held therein by a pair of metal rings or frames 5, 6, which embrace the frame 4 on opposite sides and overlap the opening and the edge of the glass therein. Preferably the metal rings 5, 6, are struck up of sheet metal and are beaded alon their inner edges 7, 8, the beading overlapping on both sides of the joint or space between the outer edge of the glass and the inner edge of the frame 4. Means, to be presently described, are provided for drawing the metal rings closely against the intermediate frame, and within the beads 7, 8 are placed filling rings 9, 10 of medium hard rubber or the like which, when uncompressed, are or may be substantially round in cross section, but

may be compressed by the beads into the form shown in Fig. 2 in which they are respectively flattened against the frame at 11 and against the glass at 12, and to some extent forced into the space between the frame and glass as at 13. Thus, these gaskets 0r filling rings firmly hold the glass in correct relation to the wooden frame not only preventing sidewise movement of the glass but also movement edgewise or in the plane thereof. The outer edges of the rings are struck up or spun inward as at 1 1 to extend over the outer corners 15 of the wooden frame toward each other for a purpose which will appear. Any suitable means may be used for securing the metal rings or frames together, but preferably I employ screws 16 which are spaced at suitable intervals about the frame and provided with nuts 17 upon their threaded ends.

My invention is applicable to both single and double curtains, 6., curtains which have but one thickness, and curtains which have an outside fabric and a lining, and in the drawing the invention is shown as applied to the latter, 18 being the outer fabric and 19 the lining. The fabrics 18 and 19 extend between the metal frames or rims, and the frames at on opposite sides of the latter respectively, and also extend between the rubber gaskets or fillers 9, 10, and their respective metal rings. Thus when the metal rings are drawn tightly against the intermediate frame the fabrics are clamped between the rings and the frame and also be tween the rings and the rubber gaskets. Furthermore the fabrics are bent about the angles 15 of the frame and again about angles formed by the beading at the inner edge of the meta], rings, and are thus securely held to the frame. The nuts 17 are coned and the openings 20 in the plate 5 through which they extend are correspondingly reamed andtapered so that the nuts not only press the metal rings or frames toward each other and against the intermediate frame, but also compress the edges of the fabric 18 which is commonly of very stout material about the screws against or into the fiber of the frame 4, thus providing an additional grip upon the fabric.

The metal rims or frames may be plated or polished or finished in any desired manner, and preferably the screws and nuts are similarly treated so as to present an attractive appearance.

The window is preferably assembled with the curtain before cutting the openings therein which are to be closed by the glass, and after the fabrics have been clamped to the frame a knife is drawn along the edges ofv the inner rims of the metal frames and the curtain fabrics neatly cut away.

It will now be recognized that my invention provides a simple and secure means for holding the glass window in position which may be quickly and readily applied, is inexpensive to manufacture, and by reason of its construction adds but little to the weight of the glass and curtain.

I claim:

1. In a device of the class described, a glass, an intermediate frame surrounding the glass, a pair of clamping frames on opposite sides of said intermediate frame and overlapping the edge of the glass and the edge of the intermediate frame, annular recesses in. the overlapping edges of said frames, and gaskets in said recesses.

2. In a device of the class described, a glass, an intermediate frame surrounding the glass, a pair of clamping frames on opposite sides of said intermediate frame, beads struck up on the inner edges of said clamping frames and overlapping the edge of the glass and the edge of the intermediate frame, andgaskets within said beads engaging the abutting edges of the intermediate frame and glass.

3. In a device of the class described, a

glass, an intermediate frame surrounding the glass, a pair of clamping frames the outer edges of which project toward each other about the outer edge of the intermediate frame and the inner edges of which are formed with outwardly extending beads overlapping the joint between the glass and intermediate frame, gaskets within said beads bearing upon the glass, and means for forcing the clamping frames together.

4. In a device of the class described, a glass, an intermediate frame surrounding the glass and of a thickness substantially equal thereto, clamping frames on opposite sides of said intermediate frame, and extending beyond the inner edge thereof and overlapping the edge of the glass, the inner edges of said clamping frames being struck up to form a hollow bead extending over the joint between the intermediate frame and the glass, a compressible gasket in each said head engaging both the glass and the frame. and means for drawing the clamping frames together.

5. In a device of the class described, a glass, an intermediate frame surrounding the glass and of a thickness substantially equal thereto, clamping frames on opposite sides of said intermediate frame, formed at their respective inner edges with hollow beads overlapping the joint between the frame and glass, compressible gaskets in said hollow beads, curtain fabric intermediate said clamping frames and the respective gaskets and intermediate frame, and means for drawing the clamping frames together.
